Experimental tests on the out-of-plane response of RC columns subjected to cyclic tensile-compressive loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso, Lisandro Arturo Jimenez Roa

Over the last few years the increasing demand of housing for low income population in Colombia and several neighboring countries, associated to the significant increase of cost of land, has prompted construction companies to build medium to high rise reinf ...

Influence of Lap Splices on the Deformation Capacity of RC Walls. I: Database Assembly, Recent Experimental Data, and Findings for Model Development

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini, Ovidiu Prodan

Recent postearthquake missions have shown that reinforced concrete (RC) wall buildings can experience critical damage owing to lap splices, which led to a recent surge in experimental tests of walls with such constructional details. Most of the 16 wall tes ...

The DEMO wall load challenge

Ambrogio Fasoli, Jonathan Graves, Jan Horacek, David Pfefferlé, Samuel Lanthaler, Bernhard Sieglin, Hartmut Zohm

For several reasons the challenge to keep the loads to the first wall within engineering limits is substantially higher in DEMO compared to ITER. Therefore the pre-conceptual design development for DEMO that is currently ongoing in Europe needs to be based ...

Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi

Empirical drift capacity models for in-plane loaded unreinforced masonry (URM) walls are derived from results of quasi-static cyclic shear-compression tests. The experimentally determined drift capacities are, however, dependent on the applied demand, i.e. ...

Thick domain walls in non-magnetic ferroics

Alexander Tagantsev, Petr Yudin, Konstantin Shapovalov

Recent developments in the physics of non-magnetic ferroics identified possible functionality of domain walls in these materials, which specifies the current interest to the internal structure of the walls. In this context, the wall thickness itself can be ...

Wall-Roughness Effects on Flow and Scouring in Curved Channels with Gravel Beds

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca

Due to a complex three-dimensional flow pattern, the outer banks of river bends are predisposed to erosion. When endangering civil structures, preventing measures to mitigate this erosion are thus required. Vertical ribs at protection walls for scour reduc ...

Size effects in drift capacities of URM walls

Katrin Beyer, Sarah Petry

Examining the results of a large set of quasi-static cyclic tests on unreinforced masonry (URM) walls showed that the drift capacity of URM walls reduces with increasing wall size. Such a size effect is of concern since most wall tests were carried out on ...

Influence of spandrel modelling on the seismic assessment of existing masonry buildings

Katrin Beyer

The paper discusses different modelling assumptions for spandrels in equivalent frame models and their effect on the global response of the wall. The topic is motivated by the following issues: i) reliable and practice oriented numerical tools constitute a ...

Formation of charged ferroelectric domain walls with controlled periodicity

Nava Setter, Dragan Damjanovic, Alexander Tagantsev, Tomas Sluka, Petr Bednyakov

Charged domain walls in proper ferroelectrics were shown recently to possess metallic-like conductivity. Unlike conventional heterointerfaces, these walls can be displaced inside a dielectric by an electric field, which is of interest for future electronic ...

Bent Ferroelectric Domain Walls as Reconfigurable Metallic-Like Channels

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Tomas Sluka, Enrico Colla, Petr Yudin, Ludwig Feigl, Konstantin Shapovalov, Xiankui Wei, Arnaud Robert André Crassous

Use of ferroelectric domain-walls in future electronics requires that they are stable, rewritable conducting channels. Here we demonstrate nontherrnally activated metallic-like conduction in nominally uncharged, bent, rewritable ferroelectric-ferroelastic ...

An indirect criterion for the laminar to turbulent flow transition in shear-driven annular liquid films

John Richard Thome, Andrea Cioncolini

An indirect method to identify the laminar to turbulent flow transition in shear-driven annular liquid films has been developed and used, together with literature measurements of the velocity profile, to approximately resolve the near wall structure in she ...
